Contents

This repository contains the following directories:

• models: Directories containing input files for describing and running the models used in this manuscript.
• meshes: gmsh input files used in the models

Running the Models

• Install TerraFERMA: To view and run these models will require building and installing the open source code TerraFERMA.

• Running Models: If the software is installed successfully the models can be run from within each subdirectory using

$ tfsimulationharness --test <filename>.shml

where <filename>.shml is the name of the simulation harness file that controls parameter sweeps and parallelization options. Models are described (boundary/initial conditions, timesteppers, weak forms, solvers etc.) in the TerraFERMA markup language files with suffix .tfml.

• Generating meshes: The meshes for this problem can be generated by running (in the meshes directory) the following commands

$ gmsh -2 <filename>.geo
$ dolfin-convert <filename>.msh <filename>.xml

• Viewing Input files: both .tfml and .shml files can be viewed and changed using the diamond GUI with

$ diamond <filename>.tfml
